There are three proposals for the floor plan. Each of them has different approach through the house. The one chosen to be more elaborated is the one that fulfills your requirements mostly. The supportive walls are only reduced in the middle without touching the corners. When the corridor is positioned in the middle of the house, it offers more view and and more open space to the plan, while remaining practical with the proper surface and spread of the used spaces.

The entrance stays the same, while the kitchen and the hall are linked together by shifting partially the supportive wall. Both of the wet spaces are enough in size, one is in front of the kitchen while the other is more enlarged to have enough space for the bathtub and shower. There are chosen sliding doors for each of the room to achieve more flexible movement through the house. The wardrobe is designed with the same style and furnishing as the bedroom to create the idea of one larger connected room even though it is separated by the corridor. Since the working room is one of the most dedicated area of the house, the furnishing corresponds simultaneously to a classical and modern one. It also serves as the hostess room of the house with the glass wall in front of the corridor and with the stylish couch for guests.
Hoping that this design fulfills your necessities!
Best Regards!
